As the plot is written on the internet: Jeong-mi lives alone with her older sister after their parents left for another country. She often uses the net to upload self-made videos, while in disguise, to garner internet notoriety. With the help of a friend, she got her hands on a blocked or forbidden video illegally. Unfortunately, a short time after, a series of escalating and horrifying events unfold to everyone who watches it. The cursed video clip is turning the whole internet world upside down; the image of a horrifying girl carrying blood-stained rag doll never stops playing on the computer and keep opening in another window when you try to shut it down. When her sister Jeong-mi (Byeol Kang) gets a strange video clip, saying it's a cursed one, Se-hee (Bo-yoong Park) doesn't believe her. Jung-mi says whoever sees the clip is doomed to death, though Se-hee doesn't pay attention to what her sister says.
But she gets scared when Jung-mi becomes lunatic after seeing the clip and starts to dig into the roots of haunting story about the video clip, with the help from her boyfriend Joon-hyeok (Won Joo) who works at the the Cyber Investigation Unit of Police. However, when Jung-mi suddenly disappears during Se-hee's investigations, she finally decides to click herself the cursed video clip to find the clue to save her sister.
